This howto needs to open your smartphone, so do it on your risk.
Read this tutorial entirely before begining anything.
This memory change will completely erase the content of your phone. Backup it before.
Tools Needed

Now, you need to remove the bottom cover. To do this, insert the plastic card inside, and pull upside gently.
Take the screwdriver. At minimum, you will need to remove screws marked by red and green arrows.
Now, pull the plastic framework upside with your finger, to get access to the MicroSD card reader
The MicroSD card is protected by a “metallic” sticker. Unstick it, and tear it below the plastic framework. You cannot remove it completely
Now push the memory card in his reader with the tweezers : you will here a clic. Release, the card will be ejected
Take the MicroSD card with the tweezers, and remove it
There you are. Now insert your brand new memory card, and reassemble your phone following the previous steps.
Once your phone is reassembled, put your SIM card, the battery, and close the cover.
To turn it on, push the two volume buttons, and keep them pushed while pressing the Power button
Keep the volume buttons pressed until you see this message

Is there a way that you can install Android OS on the HTC HD7? I have the HD7 and the Windows software is not that impressive. WP7 is too buggy and the Apps available are pretty much useless. I should have got the HTC Desire HD. I think that it will be ages before Microsoft will come up with some decent upgrades to their software…
Please look for XDA forum. You will get the answer over there
